01. Start / Run / Services.msc / OK.
02. Right-click Microsoft Exchange System Attendant and press Stop.
03. Right-click Microsoft Search and press Stop.
03. Run Recreatedefpol.exe.
04. Insert the Exchange Server CD.
05. Open a CMD.EXE window.
06. Type <CD_Drive:>\Path_Of_i386_Folder\setup /domainprep and press Enter to reset the Exchange Server permissions.
07. Type secedit /refreshpolicy machine_policy /enforce and press Enter.
08. Type secedit /refreshpolicy user_policy /enforce and press Enter.
09. Type Eventvwr.msc and press Enter.
